The \Appearnace of Man\" from Louis Figuier's 'Earth Before the Deluge' 1863 (above), and below from the same book in its sixth edition of 1867. Engravings by Riou. In 1863, a distinctly Eden-like scene sees a couple gaze out over a benign creation of contemporary animals. In the lower 1867 view the author was forced by recent developments in mainstream geology to promulgate a cave-dwelling tribal view of the first humans. They are surrounded by beasts both living and extinct. This change of emphasis was a result of the recent work of Boucher de Perthes, Falconer, Prestwich and Evans in establishing the case for human antiquity and coexistence with extinct megafauna. Sir Charles Lyell's acceptance of this thesis probably caused Figuier's choice of the later representation. The handaxes are wrongly shown hafted (after Boucher de Perthes). See J.S. Rudwick \"Scenes from Deep Time\" 1992."
